In the app you can adjust the colours, fog density and bow width. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Fogbow FAQ
How do I set Fogbow as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Fogbow in the library and click Set as Screensaver. macOS starts it whenever your Mac is idle, exactly like a built-in screensaver.
Can I use Fogbow as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Fogbow plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Fogbow free?
Fogbow is included in SCRNSVRS Unlimited. It's free for your first 7 days; after that Unlimited is $1.99/month or $9.99/year (€1.99/month or €9.99/year) for every screensaver, including new ones. It can also come up in Free this month, when 25 premium screensavers are free for everyone.
Is Fogbow a video loop?
No. Fogbow is rendered live on your Mac with Metal, so it never repeats and stays sharp on any display size. The clip on this page is a screen recording of the real thing.
Will Fogbow slow down my Mac or drain the battery?
No. SCRNSVRS drops to 30 fps on battery and stops rendering when the wallpaper is covered by a full-screen app, so Fogbow costs next to nothing in everyday use.
Which Macs does Fogbow run on?
Fogbow needs macOS Tahoe 26 or later.
